I had the PPK/s about 30 years ago. It was a lemon. I and anyone else who shot it had the magazine drop out while shooting. I took it back to the gun shop I bought it from and they told me I was hitting the mag release. I was not. They said they tested it and could not make it happen to them. They were known to not be the most honest and I stopped going to them after this.

This type of thing can happen with any gun. The thing about all PPK style guns with me is they cut 2 groves on top of my hand during recoil. Bad enough to bleed. So even though I like the idea of the PPK, I avoid them because of the cutting issue.
